Abstract (en)

[origin: WO9616926A1] A compound of formula (II), wherein n is 1-5, Z is a radical that is stable under catalytic hydrogenation conditions, p is less than 5-n, X is a radical capable of undergoing hydrogenolysis, and q is from 0 to 5-(n + p), is subjected to catalytic hydrogenation in a catalyst-containing liquid medium under hydrogen pressure. The compound of formula (II) is fed into the medium gradually so that the content of the compound of formula (II) in the liquid does not exceed 1000 ppm by weight. A compound of formula (I) is selectively formed.
